The electron band structure of Tb metal has been reexamined by means of angle-resolved photoemission experiments on Tb(0001) samples free of Fe impurities in the surface region. Comparison of the present data with those collected from an Fe-contaminated sample shows that the presence of Fe in the surface region caused a shift of the top portion of the 6{ital s}-5{ital d}{sub 3{ital z}}{sup 2}{minus}1-type {Delta}{sub 1} band toward larger binding energies by approximately 1 eV. The energy position of the top of the {Delta}{sub 1} band ( {Gamma}{sub 4}{sup {minus}}) is {minus}2.6 eV. The agreement with the result of the relativistic linear-muffin-tin-orbital calculation reported earlier ({ital E}{sub {Gamma}4}{sup {minus}}={minus}2.3 eV) is markedly improved.
